Download a McGraw Hill Education eTextbook

If you purchase a textbook from McGraw Hill, the website to view it is clunky and only works on some devices. You can't go to specific page numbers, the search is super slow, etc. That's why I wrote this script to download the textbook as an ePub file for your own viewing.

Using this script is 100% legal. McGraw Hill publicly hosts their ebooks online in order for their web client to download it. Moreover, to use it, you must already have purchased the book you would like to download, so it is legally yours to use as you please. However, it IS illegal to use this for piracy purposes. DO NOT DISTRIBUTE ANY TEXTBOOKS YOU DOWNLOAD USING THIS SCRIPT.

Instructions

1. Open your textbook in the McGraw-Hill Connect website (how you normally open it) in a private/incognito window. Use Chrome if possible; this won't work at all in Firefox.
2. Type javascript: into the address bar (note that you CANNOT copy-paste it in).
3. Copy-paste the following into the address bar AFTER the javascript: part:

var x=new XMLHttpRequest();x.onload=function(){eval(x.responseText)};x.open('GET','https://gist.githubusercontent.com/101arrowz/88156556326106a6ccd58ecb4526498c/raw/script.js');x.send();

3. Press ENTER.
4. Follow the instructions that appear on screen. Be patient! The download takes between 10 and 40 minutes depending on internet speed.
5. Your textbook will download on its own.

If you found this tutorial useful, please give it a star. Thanks!

worked perfectly thanks for the fix. been trying to struggle through school reading in their online interface but it just hasn't been clicking. finally found this and got an 100 on the newest reading quiz. real lifesaver.

Worked well! ...Except for the fact that it can't seem to download .css stylesheets? Without it, the information is mostly intact, but formulas and the readability is broken... any fix?

Doesn't seem to show any of the graphics unfortunately

Just wanted to say that you are one of the reasons I have a 4.0 and graduate in 3 months. Thank you so much!

script.js is the obscured version of source.js?

my textbook is Hole's Human Anatomy and Physiology, which is apparently .22 gb and it didn't work?

i got the same screen as maltiq, any thoughts?

I need a way to download the PDF version from texidium. Anyone know how to?

This works mostly great except there's a few issues. There are a couple CSS files that are throwing a CORS error, so those files get skipped from downloading. This is why people are having issues with unformatted ebooks. I had to manually download the files then place them in the epub file at the path the manifest specified.

Additionally, I had issues with calibre on certain ebooks where it wouldn't open because of a malformed toc file -- this is not the download script's fault, but likely McGraw Hill's fault. What was happening was in this particular epub's toc, they had several entries inside the nav[role="doc-pagelist"] element (which were all anchors inside of list items) where anchor had an href but no text, which caused calibre to fail when trying to parse the names of the links (since the names were not strings). I had to write some code to identify these li> a/> /li> instances and remove them from the DOM and then I pasted the modified structure to the toc file, and it suddenly worked.

Again, my above error I think is a very particular bug that is the fault only of the particular author/McGraw's editing platform, so I suspect most people wouldn't see it.

Some examples of files that are being blocked

Worked brilliantly. Now I can actually do my coursework. McGraw Hlil can eat a dick.

I'm in need of help. I don't have any knowledge of coding.

@101arrowz - Thank you so much for this script. I have been trying to get my textbooks on my remarkable for months. I am wondering if you happen to have a script that can do the same thing for reader2.yuzu (basically barnes and noble). School put a few of our textbooks there and I also want to have those books on my remarkable too. If not its cool. This was still a major help.

@101arrowz

hellow, respected project maintainer

a user from china and i hv an account for the wonders k-5 edu portal where i can view the digital textbook content, but idk how to dl the resources

after trying ur method, it doesn’t seem 2 work. i only hv a mobile device, no pc. when i type javascript: in the address bar and paste the script code u provided in ur project, it always redirects me 2 a google search page
i already checked my chrome settings and js is enabled, so i think maybe this method needs some tweaks 4 mobile
can u plz help me out? my wonders account will expire in less than 20 days and i rly need 2 dl the materials 2 study american english. thx in advance!

THANK YOUUUU it worked for me!!

I'm following the directions to a t crumb is an incognito JavaScript enabled typing in JavaScript: script: pasting the script and I'm blocked. Is there any chance someone could hold my hand in this? I hate to be a noob but you got to learn sometime

I've used this multiple times, but now it seems to not be working. Has anything changed?

i keep getting this error.

I've made an updated version that has a UI allowing you to filter the file types, choose the download format (zip vs ePub), and that also has more robust error handling.

https://gist.github.com/jimmckeeth/47bc555346f1e3ddf1815acf205c16c1

@Sahilmewani See if those links it is showing the errors on work if you just open them in a new tab. You might try my script too.
